To /l/ZZ 'wh/0771, t 'mfc/y concern:

Be it known that I, Guantes KING, a subject of the Kingo'lI Great Britain, i'esiding' at .lhe Grange, Ashford, county ot lvliddlesex, llingland, have invented new and useful Improvements in Reciprocating Engines, ol which the following is a specilication.

lhis invention relates to reciprocatingI engines operated by the explosion ot combustible vapor or gas or by steam, compressed air, or other expansive liuid, the object being to provide what is practically a valveless engine.

According to the invention Al construct iny improved engine el a cylinder, a piston, and a crank-shaft with a ily-wheel, as usual; but in lieu el" the ordinary inlet and exhaust valves l. provide for effecting the admission and exhaust by imparting rotary motion to the piston, which has a port or ports adapted to act in conjunction with ports in the cylinder.

ln the accompanyingdrawings, Figure 1 is a longitudinal section of onet'orin el internalcoinbustion engine constructed according' to the invention. Fig. Qis a sectionalplan view thereof; and lig, 3 is a development o'l' the cylinder, showing' the inlet and exhaust ports therein. Fig. t is a longitiildinal section o'lf a niodilied ctmstruction et' internal-combustion engine constructed according' to the invention. Fig. 5 Figs. 6 to l0 are views ot' details hereinafter described.

Referring lirst to the arrangement illustrated in Figs. l to 3, c represents the cylinder, which is provided with trunnions mounted in bearings c o upon a bed-plate (Z, resting upon suitable supports e. is the piston, which is adapted to bc rcciprocated within the cylinder a, the inner end ot' the piston f being' provided with a tubular extension ,(7, litting over aplug in the outer end ol.'I the cylinder (t. The piston propeigf, .is hollow and is directly coupled with the crank-shaft vf, mounted in bearings if: /fi upon thebed-plate (Z, the connection being etl'ected by the end j, the base of which is rotatably held in the end ol" the piston if. The outer end et the piston f has rigidly secured to it the bevel-wheel l, which gears with the bevel-wheel fm, keyed upon the crank-shaft i', so that the said is a sectional plan view thereof, and' crank-shalitr' is rotated by the reciprocation ot the piston the gear-wheel fm. rotates the wheel and thereby imparts rotary motion to the pistonf within the cylinder n. ln the arrangement shown in the drawings the bevelwheel m haltl the diameter of the bevel-wheel l, so that the pistonfinakes one .revolution for every two revolutions oi' the bevel-wheel 'la or crank-shaft v'. The piston is provided with a port la, which as it rotates is brought into coincidence with the inclined inleiii-port o in the cylinder rz', to which port the motive tluid is supplied through the pipe 72 and with the exhaust-port (1 in the cylinder, which is merely an inclined slot formed in the *all ot the'cylinder, as clearly indicated in Figs. l and 2.

lhc engine illustrated is arranged to work on the Beau de Rochas or Otto cycle, and during the lirst outstroke el" the pistoni/iconibustible vapor is drawn through the pipe y) and ports o and w, into the tubular extension f1 of the piston, the said piston beingl rotated through a quarter oll a revolution during this ontstroke. WV ith the lirst return stroke the charge is compressed in the usual way, the piston being rotated a further quarter oll a revolution. The charge is then ignited and duriiig the next outward or working stroke ot the piston the latter is rotated a further quarter ol'I arevolution, which brings the port a opposite the exhaust-port g, so that during the final or exhaust stroke the products ot combustion escape through the said port r] into the atmosphere, the cycle then beginning (le Although the engine above described operates upon the Otto cycle. it will be clear that any other ot the usual cycles can be made use ol. 'lhe ignition is preferably effected by means el` an electric spark, although other forms ol ignition can be employed, it' desired. ln the drawings, fr and s represent the sparking points, t a switch in the primary circuit, which is normally broken, and fr a cam-sur- Aface or tappet on the rotating piston, which strikes the switch z5' once each revolution and so completes the electric circuit and causes sparking to take place.

ln the engine illustrated in Figs, 4l to l() the l'OO cylinder ft' oscillates upon the bed-plate d' in the same manner as in the arrangementbei'ore described, and the piston f is directly connected to the crank-shaft t" also in the same manner. In lieu, however, of continuously rotating the piston, as before, I now provide for intermittently rotating the same, and Jfor this purpose the end of the piston is provided with a disk a, having a number of gear-teeth w, with which engage gear-teeth or cam-surfaces el; upon the crank. Figs. 6, T, and 8 are an end view, a side view, and a plan, respectively, illustrating the gear or cam teeth upon the crank-pin, while Figs. 9 and IO are respectively an end view and -a side view of the teeth upon the end or' the piston. Furthermore, in this arrangement a number of port-holes z/ y are provided in the piston itself, the said holes following a curved path, as shown in Fig. 4, and theintermittent rotation of the piston bringing these ports successively under the simple inlet-port and the elongated outlet-ports', providedin the cylinder a. The cylinder instead of being arranged to oscillate may be stationary. In this case the piston is connected to the crank by a rod in any suitable manner and rotary motion is imparted to the piston by the means as aforesaid or by other suitable means.

Then the engine is to be operated by steam or other expansive luid,the piston is arranged to make one rotation or more or less for each rotation of the crank-shaft, and apertures are formed in the cylinder as required for the admission and also for the exhaust, so that the piston receives an impulse at each revolution instead of at every other revolution, as in thc case of an internal-combustion engine.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is* l. In a reciprocating engine, the combination of a cylinder, a piston, a crank-shaft rotated by the piston, means for rotating the piston in the cylinder to control the distribution of the motive luid, an igniting device and ignitcr-eontrolling mechanism including a part carried by said rotating piston, substantially as described.

2. In a reciprocating' engine, the combination of a cylinder, a piston, a crank-shaft rotated by the piston, means for rotating the piston in the cylinder to control the distribution of motive iuid, an igniting device, ignitercontrolling mechanism mounted on a stationary part and a cam mounted on the rotating piston for engaging' and operating the ignitercontrolling device, substantially as described.

3. In a reciprocating engine, the combination of a cylinder, a piston, a crank-shaft rotated by the piston, means for rotating the piston in the cylinderl to control the distribution of motive iiuid, an igniting device, a circuitcontroller for said igniter mounted on a stationary part and having a movable contact and a cam mounted on said rotating piston for engaging said movable contact, substantially as described.

LI. In a reciprocating engine, the combination of an oscillatingcylinder, a piston,a crankshaft rotated by the piston, a tubular extension at the rear of the piston, ports in the cylinder and piston extension and toothed gear, such as bevel-gear, for rotating the piston from the crank-shaft, substantially as described.

5. In a reciprocating engine, the combination of an oscillating cylinder, a piston, a crankshaft rotated by the piston, a tubular extension at the rear of the piston, ports in the cylinder and piston extension, means for rotating the piston in the cylinder and an igniting device controlled by the rotating piston, such as a cam-surface on the said piston for making and breaking an electric circuit, substantially as described.

6. In a reciprocating engine, the combination of an oscillating'cylinder,a piston, a crankshaft in connection with the piston, a bevelwheel upon the crank-shaft, a bevel-wheel upon the piston, gearing with the bevel-wheel upon the crank-shaft for continuously rotat- CHARLES KING.
